Abstract
S obzirom na razvoj energetske elektronike, te isto tako i upravljačkih sklopova, došlo je do različitih metoda što se tiče upravljanja samih elektromotornih pogona. To upravljanje je moguće uz pomoć momenta, tereta i brzine vrtnje elektromotora. Kod upravljanja pomoću brzine vrtnje postoji veliki broj metoda kojima je zadaća dobivanje što je moguće bolje izlazne karakteristike, te u konačnici kako bi cijeli sustav bio čim više učinkovitiji. Kao najprihvatljivija metoda upravljanja je izmjena frekvencije napajanja, pa su slijedom toga statički pretvarači frekvencije pronašli svoju veliku primjenu unutar sustava. Velika pažnja se mora posvetiti i sigurnosti, te zaštiti elektromotornih pogona, kako bi se osigurala zaštita osoba u blizini takvog pogona, te nakon toga i u svrhu produljenja ispravne eksploatacije stroja. Postoji određeni broj uvjeta na čiji se račun odabire način upravljanja i vrsta motora, a to su: vrsta opterećenja, faktor snage, uvjeti okoline i troškovi održavanja. Nakon analize tih uvjeta zadovoljena je funkcionalnost cijelog sustava.
Abstract (english)
With regard to the development of power electronics, as well as control circuits, there have been various methods regarding the control of the electric motor drives themselves. This control is possible with the help of torque, load and speed of the electric motor. In speed control, there are a number of methods that aim to get the best possible output characteristics, and ultimately to make the whole system as efficient as possible. The most acceptable control method is to change the supply frequency, and consequently static frequency converters have found their wide application within the system. Great attention must be paid to the safety and protection of electric motor drives, in order to ensure the protection of persons in the vicinity of such a drive, and thereafter in order to prolong the proper operation of the machine. There are a number of conditions on which the control mode and type of motor are selected, those are: type of load, power factor, environmental conditions and maintenance costs. After analyzing these conditions, the functionality of the entire system is satisfied.
